KEY VALUE
hugepage_size2m Number of 2M huge pages, any positive integer
hugepage_size1g Number of 1G huge pages, any positive integer
Allocated hugepage size should not exceed 60% of available memory on
the node. For example, c2d-highcpu-4 has 8GB memory, total allocated
hugepage of 2m and 1g should not exceed 8GB * 0.6 = 4.8GB.
1G hugepages are only available in following machine familes: c3, m2,
c2d, c3d, h3, m3, a2, a3, g2.
Note, updating the system configuration of an existing node pool
requires recreation of the nodes which which might cause a
disruption.
